While I'm not a fan of Sizemore or his abuse of women, don't use your power, Perez, to get something started that tries this guy in the media before police have anything on him.

It's very tiring as a member of the public to see blogs and the mainstream media convicting people before there is any proof of guilt. If you want to maintain a modicum of respect for what you do, don't go down that road on this Sizemore story.

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
